I use PTH Racing
oil.
In the interest of full disclosure, I have a financial interest in PTH.
PTH Racing
Oil’s base stock is a 100%
synthetic blend of Group IV (PAO) and Group V (Polyesters). PTH’s
oil has high levels of
zinc, phosphorous, and other additives to prevent premature wear, and reduce friction.
Zinc and phosphorous are critical on high lift high acceleration solid lifter camshaft engines. PTH also uses high levels of calcium both for its detergent properties and very important for Cobra owners, acid neutralization. Acid neutralization is important for controlling internal engine corrosion. Where PTH oil really shines is in High Temperature High Shear (HTHS) viscosity tests. HTHS is a measure of how the oil will break down under high temperature and high shear. These additives coupled with an outstanding HTHS make PTH oils especially good for endurance race engines, high performance street and high performance/racing boat engines. Due to the high additive levels, PTH’s oil is unsuitable for engines equipped with catalytic converters.
PTH Racing Oil is available in three weights, 5W-30, 10W-40 and 20W-50.
